Motion and Thermal Energy Review

When a thermometer is heated, the red liquid inside the thermometer moves up. This is mainly because:

• The red liquid is thin and can easily move up the thermometer.

• Hot liquid is lighter.

• The glass thermometer gets hot.

• The molecules in the liquid move faster and spread apart.
